Why it matters

Built for marketplace scale, not a one-time cleanup

Supplier growth is what breaks a marketplace catalog: every new brand or seller arrives as its own spreadsheet, feed or PDF, with its own naming, categories, attributes and language. The result is duplicate and inconsistent listings, missing attributes that quietly kill discoverability, and filters and search that stop working exactly when the catalog is growing fastest. Claro acts as the execution layer for catalog operations — ingesting supplier data in any format, normalizing it to your taxonomy, deduplicating records, enriching missing attributes and validating against your rules — and keeps PIM, search and commerce systems in sync as suppliers and assortments keep changing.

What that looks like on a real file

Two merchants, one SKU: 500 g in one feed, 1 pc in the other. Text similarity says they’re the same listing. Your stock count says otherwise.

Claro writes back through files and APIs rather than certified connectors, so this list is a guide, not a limit.

The problem

What supplier growth does to a marketplace catalog

Multiple data sources per seller — spreadsheets, feeds, PDFs, manual uploads — arrive with inconsistent naming, categories and attributes.

Duplicate and inconsistent listings pile up across suppliers and sellers.

Missing or incomplete attributes break filters and hurt product discoverability.

FAQ

Marketplaces & aggregators: common questions

How is this different from a PIM?

Upstream of it. A PIM stores and publishes what you’ve already decided is true. Claro decides it — resolving identity across sellers — before it reaches the PIM.

Can it handle sellers listing the same product?

That’s the core of it. Products are clustered by real identity, not surface text, and every proposed merge carries a confidence score and stays reversible.

How fast can a new seller catalog go live?

Send one real feed and you get a matched, deduplicated sample back within five days — a full pilot is live in about eleven business days.
